DISK-FEEDER.

Specification of Letters Patent.

A1,)atentd June 1, 1920.

To all 'whom t may concern: Y

Be it known that I, FLOYDv D. S'rowE, of Wilmington, in the county of New Castle, and in the State of Delaware, have invented a certain new and useful Improvement in Disk-Feeders, and do hereby declare that the following is a full, clear, and exact descri tion thereof.

y invention relates especially to conveyers adapted for feeding blanks, and it relates more particularly to an apparatus designed for feeding blanks in the orm of disks, such as those used for' providing the ends of cylindrical sheet metal kegs, al though it is applicable to many other uses.

The object of my invention is to provide a conveyer which will effectively andfumformly feed blanks, as 4for example, blanks received from a blanking press and convey these blanks to an elevated position where they may be fed into the forming press or other apparatus in which the blanks are to be utilized. A further object lof my invention is to provide an apparatus of this k1nd in which the blanks are discharged from the conveyer into the forming press or other apparatus in which vthe blanks 'are to be used one at a time and at given intervals of time, and in which, furthermore, any blanks in addition to those needed for the forming press or other apparatus are dischargedl separately "by the conveyer without being fed to the forming press or other apparatus referred to. f

While my invention is capable of being carried out in many different ways, for the purpose of illustration, I have shownonly one form of my invention in the accompanying drawings, in which,

Figure 1 is a vertical elevation partly in section of a conveyer made in accordance with my invention.

Fig. 2 is a front .View of the' same. Fig. 3 is a top vlew of the same, and

Fig. 4 is a transverse section taken on y une 4 4 of Fig. 1.

In the, drawings I have shown an inclined conveyor which is supported upon a base 1, having ears 2,' with holes to secure the apparatus to the floor or other support.

'This base 1 isY provided with three bushings 3 to receive ends of "three conveyer screwsl 4, 5 and 6 to the ends of which are secured gears 7, 8 and 9. The shafts are driven in the same direction and at the same speed through the intervention of an idler gear 10 carried on a stud shaft 11 which extends up through the base 1f and is secured thereto by means of a nut 12. The base 1 has a gear box 13 attached to the under surface.

thereof by means of bolts 14 and nuts 15 for the purpose of inclosing the gears 7, 8, 9 and 10. Uponthe upper face of the base 1 there are a pair of. arms 16 to support a platform 17 which receives the blanks, such for example, as disk blanks, the platform 17 being attached to the arms 16 by screwsy 18. At its side the platform has a pair of lateral guides 19 so as to guide the blanks to the screws 4, 5 and 6. The platform 16 also has a pair of tracks 20 to allow the blanks to slide more readily7 thereon.`v The.)

base 1 also receives four rods 21, which are secured to the base 1 by means of'nuts 22 and which support on their upper ends an end frame 23, which end frame is maintained vai-fvr in place by nuts 24 on the ends yof the rods 21. The tw o screws .4 and Gvh'ave their upper ends Journaled 1n the end frame 23;.

The screw 4, however, passes through the end frame 23 and is provided above the end lframe with a beveled/gear 25 which meshes with a beveled gear 25a on a shaft 26 supl port-edvby bushings 27 in bearings 28 on the end frame 23. The shaft26 has a pulley 29 on its end to receive power from any suitable source. The beveled gears 25 and 25a are carried in a gear boX 30 which is formed on the end plate 23, and which has a removable cover 31 for inclosing said gears.

The screw 5 is shorter than the` screws 4 and '6 and terminates below the"v l discharge plate 35, having tracks 35'and side4 guides 35", projects into thecon've'yer beneathy the end plate 23 and'over the end of the screw'j to receive the blanks-as they fall by gravity from the conveyer and over the end of the screw V5. This discharge plate is supported upon the two rear rods 21 by clamping brackets 36. Near its end the discharge plate 35 is provided with a pair of stop pins 37 and 38 operating through open` ings in the discharge plate, which are screwed into the ends yof a rocking lever 39,

pivoted yto the underside of thefdischarge 10 plate 35 in a bracket 40 on a shaft 41. The end of the shaft 41 vhas van upwardly directed arm 42 to which is vattached a connecting Arod 43 which connects the arm 42 with an l i above the discharge plate 35. there is secured eccentric 44 whichv may be attached to a shaft 45 carried by a forming press 'o r any other apparatus, to which the blanks are to be fed from the conveyer. Immediately to the same a side chute 46 which is secured to the dischargeplate by means ofadjusting screws and nuts 48 passing through ears 49 and 50 yupon the discharge plate 35 and the side chute 46 respectively.

v withdraw the pin 38 and .elevate the pin 37. f

` beveled gears 25 an he side chute 46 Chas a plurality of tracks 46 and side uides 46". pivoted guide 51 is supporte in journal brackets 52 at the .front of the side chute 46 'and has three forwardly -directed guiding arms 53 and a rearwardly directed arm 54 which operates ina slot 55 in the side chute 46 and a slot 56 in the discharge .plate 35.

In the operation of the conveyer, blanks are fed atintervals' to the `platform 1.7 froma blankin press or. in any other suitable manner. he screws 4, 5 and 6, bein other upwardly in the'space between the several screws in an effective and uniform`manner i until the blanks have been conveyed above the end of the screw 5. -The inclina- ,tion of screws 4, 5 and -6 is advantageous in lthat .the blanks, whilebeing fed, rest on screw 5 and are `ided upwardly `by the combined action o the three screws which still permit removal of a defective blank at 'any .point in its travel along the ls rews,

since with the inclined arrangement the screws need not inclose the blanks so asto f The pin 37 in its elevatedposition then stops ro-` tated from the pulle 29 by means o the n 25a4 and the gears7, 8, 9 and-Vv 10, conveyr the blanks'one after an-y the blank which falls by gravity in front of the pin 38 to a position in frontrof the .pin 37 When the eccentric 44 moves in such a manner as to withdraw the pin 37 from above the discharge plate 35, the

blank which has been retained by the same falls by gravity from the end of the discharge plate 35 into a forming press or any other apparatus designed for receiving the blanks. In this movement the pin 38 will be again elevated so as to prevent the nextv succeeding blank from being fed into the lforming press vor other apparatus designed for receiving the blanks. he blank which is retained in this manner by the pin 38 cannot be fed into the forming press or other apparatus referred to until the eccentric has made another complete revolution, so as to first withdraw the pin 38, 'elevating the pin v i 37 and then subsequently withdraw the pin 37, elevating the pin 38. Y After the conveyer has begun to operate, in the normal operation thereof, there will be a blank fed into the discharge plate at about the time that or other'apparatus. When the' pin 38 is ele vated there will thus normally be a blank held in place above the pin 38 beneath the arm 54. Should anotherblank be f ed to the discharge platform while the parts are in this position the guiding-arm 53 will lift said blank into the side chute 46, where it will be discharged from the conveyingl ap '-paratus to a receptacle of any desired' character. With devices of this character only a singleblank may b e fed into the forming press or othersimilar apparatus for one revolution of the eccentric 44. Any blanks .the pin 37 has been withdrawn to release this blank to be fed into the forming press' in excess of this which are fed upwardly by f the screwsf4, 5 and 6 are discharged at the side chute 46.y 4 i. While I have described myinvention 'above in detail, I wish it to beunderstood that many changes may Abe made therein without departing from the spirit of my invention.

I claim:

1.- In a feeder, means for feeding blanks,

means for discharging the blanks one at a time, com rising a chute and a rocking detent thereln adapted to form a stopgfor each blank as itis fed, and a deflecting means for excess blanks-comprising a chute adjacent said first mentioned chute, and a rocking de-v Hector adapted to be engaged by a blank when against said detent for deliecting blanks to said last mentioned chute.

2. In a feeder, means forfeeding blanks, means for dischargingthe blanks one at a time, comprising an inclined delivery chute and a second chute for excess blanks located adjacent the same, a stopin said delivery chute adapted to be actuated periodically to permit blanks to pass along said delivery chute, and Ia deleotor engaged by a blank when against said stop for defiecting blanks to said chute for excess blanks.

3. In a feeder, a plurality of inclined screws adapted to engage the members fed,

lthe lower of said screws being shorter than the others whereby the members fed may fall away from the remaining screws, and a delivery chute adjacent said short screw.

In testimony that I claim the foregoing I have hereunto set m hand.
